Well Hi again !

The 50/50 ratio means that the weight of the car is evenly distributed front to rear.  So if the car weighs 2000 Lbs.  1000 Lbs. of that weight will be on the front tires, and the other 1000 Lbs. on the rear wheels.

In racing cars, we try to get all four tires evenly balanced so that 25 % of the weight is on each wheel when the car is ready to race, and the driver belted in. We even weigh them only when he's wearing his helmet and fire protective suit.
